The three-level filter fuel oil supplying system of the engine comprises an oil tank, a fuel oil filter part and a high-pressure jetting system, wherein the oil tank, the fuel oil filter part and the high-pressure jetting system are connected through fuel oil conveying pipes, a three-level filter mode is adopted by the fuel oil filter part, the oil tank is connected with a first fuel oil filter which is connected with a low-pressure oil conveying pump, an output of the low-pressure oil conveying pump is connected with a second fuel oil filter and a third fuel oil filter in sequence, and an output of the third fuel oil filter is connected with a high-pressure pump which is connected with an oil atomizer through a high-pressure oil rail. The filter precision of the first fuel oil filter is 25 mu, the filter precision of the second fuel oil filter is 10 mu, and the filter precision of the third fuel oil filter is 5 mu. The first fuel oil filter is installed on the side of the oil tank of a whole car, and the second fuel oil filter and the third fuel oil filter are installed on a cylinder cover of the engine. According to the three-level filter fuel oil supplying system of the engine, a filter mode of step type with 5 mu+10 mu+25mu is adopted, impurities and water in fuel oil are filtered successively, and clean fuel oil is provided for the engine continuously.
Description
Technical field
The utility model relates to engine fuel oil system, particularly a kind of three-stage filtration fuel oil supply system of motor.
Background technique
Along with national Abgasgesetz is progressively implemented, electronic controlled diesel market share amount will continue to increase, but domestic oil product far can not satisfy electronic controlled diesel to the requirement of oil product, existing two-stage fuel oil filtering system is good impurity and the moisture in the filter fuel again, cause oil-fired system component failure rate higher, can not satisfying the market to the demand of product.
Summary of the invention
The purpose of this utility model is the three-stage filtration fuel oil supply system of a kind of motor of design, impurity and moisture in the good filter fuel, and for motor continues to provide clean fuel oil, satisfying the market is to the demand of product.
The technical solution of the utility model: the three-stage filtration fuel oil supply system of motor of the present utility model comprises fuel tank, fuel oil filtration fraction, the high-pressure injection system that is connected by the fuel oil transport pipe, its fuel oil filtration fraction adopts three-stage filtration, fuel tank connects the first fuel filter, the first fuel filter connects the low pressure oil transfer pump, the output of low pressure oil transfer pump connects the second fuel filter, the 3rd fuel filter successively, the output of the 3rd fuel filter connects high-pressure service pump, and high-pressure service pump connects oil sprayer by high pressure oil rail.
The filter precision of described the first fuel filter is 25 μ, and the filter precision of the second fuel filter is 10 μ, and the filter precision of the 3rd fuel filter is 5 μ.
Described the first fuel filter is installed in the car load tank side, and the second fuel filter and the 3rd fuel filter are installed in engine cylinder and cover.
Advantage of the present utility model: the utility model adopts 5 μ+10 μ+25 μ cascade filter types that the impurity in the fuel oil and moisture are filtered one by one, for motor continues to provide clean fuel oil.The utility model is simple in structure, and combustion filters filter grade connection and reasonable arrangement, can guarantee that electronic controlled diesel is to the requirement of oil product.

The three-stage filtration fuel oil supply system of motor of the present utility model comprises fuel tank, fuel oil filtration fraction, the high-pressure injection system that is connected by the fuel oil transport pipe, its fuel oil filtration fraction adopts three-stage filtration, fuel tank connects the first fuel filter, the first fuel filter connects the low pressure oil transfer pump, the output of low pressure oil transfer pump connects the second fuel filter, the 3rd fuel filter successively, the output of the 3rd fuel filter connects high-pressure service pump, and high-pressure service pump connects oil sprayer by high pressure oil rail.
The filter precision of described the first fuel filter is 25 μ, and the filter precision of the second fuel filter is 10 μ, and the filter precision of the 3rd fuel filter is 5 μ.
Described the first fuel filter is installed in the car load tank side, and the second fuel filter and the 3rd fuel filter are installed in engine cylinder and cover.
Three fuel filters of the present utility model adopt arranged in series, realize echelon impurity screening and moisture.Concrete mode is such: under the pull of vacuum effect, be inhaled in the fuel from fuel tank in the first fuel filter on the car load, through behind the single filter, by the car load pipeline, fuel oil is transported in the low pressure oil transfer pump on the motor, through after the pressurization once, more successively through the second fuel filter and the 3rd fuel filter, realized three-stage filtration, guaranteed that the fuel oil of cleaning enters high-pressure injection system.
The car load tank side is installed the first order 25 μ fuel filters and is designed to total member, the impurity in filter fuel more than 25 μ and the most moisture, also attaches the functions such as mechanical oil transfer pump, level sensor, fuel Heating; The second fuel filter and the 3rd fuel filter all are installed on engine cylinder by fuel filter seat and cover, the second fuel filter is in filter fuel the impurity more than 10 μ, also will filter the moisture that 25 μ filter cleaners do not filter out on the car load, play the effect of second class protection; The 3rd fuel filter only has the function of impurity screening, belongs to the essence filter on the motor, and after this filters, the fuel oil of cleaning will enter high-pressure injection system.
